Original Abstract

Achieving thermal equilibrium in two-dimensional lattices of interacting nanomagnets has been a key issue on the route to study exotic phases in artificial frustrated magnets. We revisit this issue in one-dimensional artificial kagome spin chains. Imaging arrested microstates resulting from a field demagnetization protocol and analyzing their pairwise spin correlations in real space, we unveil a nonequilibrated physics. Remarkably, this physics can be reformulated into an at -equilibrium one by rewriting the associated spin Hamiltonian in such a way that one of the coupling constants is quenched. We interpret this quenching mechanism as a kinetic hinderance occurring upon demagnetization, which induces the formation of local flux closure spin configurations that compete with those energetically favored by the magnetostatic interaction coupling the nanomagnets.
